Metabolism of proteins Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?

A. Sebum

B. Urea

C. Lysozymes

D. Water

Answer Explanation:

Proteins are nitrogen-based compounds, which when broken down release ammonia. Ammonia is a toxic substance to the body, and sebaceous glands coverts it to urea.

Therefore, the Correct Answer is B.

Q #1: Building blocks of proteins Which of the following organic molecules contain both an amine and carboxyl group?

A. Lipids

B. Proteins

C. Cellulose

D. Chitin

Answer Explanation

The basic building block of the protein is ammonia, which comprises of ammino group -NH2 and a carboxyl group, -COOH.
Q #2: The Life Cycle of HIV Which of the following allows the AIDS virus, which contains RNA, to insert viral DNA into the DNA of a host T-cell after the AIDS virus enters the cell?

A. Receptor proteins located on the surface of the virus

B. The protein that makes up the capsid of the virus

C. Reverse transcriptase, an enzyme encoded by the virus

D. The phospholipids found on the envelope of the virus

Answer Explanation

The AIDS virus (HIV virus) is Class VI or Group VI in the Baltimore Classification. Based on the Baltimore Classification, this specifically involves the reverse transcriptase enzyme and it is encoded by the virus.

This is the enzyme that will produce DNA molecules from the viral RNA. This is the mechanism involved where it will use the reverse transcriptase enzyme to insert viral DNA into the genetic material of the host cell.
Q #3: If a portion of strand of DNA bases reads 5’ AGCTAGCGT 3’, what would the sequence of bases on the complementary strand read?

A. 5’ UCGAUCGCA 3’

B. 3’ TCGATCGCA 5’

C. 5’ TCGUTCGCU 3’

D. 3’ AGCTAGCGT 5’

Answer Explanation

The complimentary base pairing of DNA states that A pairs with T while C pairs with G. From the give sequence, the complimentary DNA strand will be 3’ TCGATCGCA 5’
